The best practice for dose-limiting serial synchrotron rotation crystallography was examined through anomalous signal and single-wavelength anomalous diffraction phasing of mercury-bound luciferin regenerating enzyme. Sample rotation enabled accurate data collection with fewer diffraction images than without rotation, and an increase in resolution and anomalous signal was observed up to 3.4 MGy even though specific damage occurred after an accumulated dose of 1.1 MGy.Copyright (c) 2016 International Union of Crystallographyurn:issn:1600-5775Kazuya Hasegawa et al.doi:10.1107/S1600577516016362International Union of CrystallographyThe best practice for dose-limiting serial synchrotron rotation crystallography was examined through anomalous signal and single-wavelength anomalous diffraction phasing of mercury-bound luciferin regenerating enzyme.
